Specification of Letters Patent.

Patented Feb. 13, 1917.

To all whom t may concern:

Be it known that I, JAMES WV. RUMsEY, a citizen of the United States of America, and a resident of West Berkeley, county of Alameda, and State of California, have invented certain new and useful Improvements in Door Structures for Cars, of which the following is a full and clear specication, reference being had to the accompanying drawings, in which- Figure l is a side elevation of a portion of a boX-car showing my invention applied thereto; and

F ig. 2 is a horizontal sectional view on the line 2-2 of Fig. 1.

This invention has relation to box-cars in which the door slides horizontally'back and forth across the door-opening, and, when closed, is clamped or crowded into close contact with the door-posts for the purpose of preventing admission of moisture into the car; and the present improvements are intended to provide simple means for effectively drawing the rear edge of the door to sealing relation with the door-post strucl ture, means being provided which not only prevent the entrance of moisture into the car, but which will prevent the entrance of air as well as smoke and cinders, as more fully hereinafter set forth.

In the drawings, only the right-hand portion of the door structure is illustrated, the door being designated a, the side of the car being designated b, and the two vertical members c and d composing the post .structure. Clamped between these two members c and l by suitable bolts e is a vertical plate running the full length of the post and projecting beyond the face of the car-body, this vertical projecting edge being provided with a flange g which lies parallel with the adjacent face of the car-body and at a dis tance therefrom. The outer face of the flange g preferably lies substantially flush with the outer face of the adjacent post member c. The outer boards h of the car wall abut against the abutment plate f. This abutment plate f, by reason of its being extended into the post member and beyond the outer boards L of the car wall, affords an effectual anchorage for the abutment plate, serving to throw upon the post structure directly thestrains and jars violently closing and sealingthe door.

F astened to the rear edge of the door is an angle iron, one of whose plates i extends along the edge of the door and the other of whose plates y' extends along the inner face of the door, a layer of felt or other brous or elastic substance c being clamped between this plate and the adjacent face of the door, the edge of this felt packing projecting beyond the free edge of the plate y'.

Aiixed to the inner face of the plate or iiange j ofthe angle iron, at intervals along the length of the same, are a series of cam plates-Z, each of these plates being fastened rigidly against plate y' by means of a series of horizontal bolts or rivets m extending through the plates of the` door. In the present construction I have illustrated three of these cam plates Z and it is believed that this will be a sufficient number under all oircumstances. The inner edges of these cam plates j project beyond the inner edges of the angle iron flanges jand thus form a channel between the projecting edges of the plates and the inner face of the door, which channel receives the free edge of the flange g when the door is slid to a closed position. The corners of the flange g and the cam plates Z are rounded olf so as to more certainly direct the flange g into the channel formed by the projecting edges of the plates and to insure a cam or clamping action which will, when the door is closed, draw the door closely to the post structure. When the door is closed, it will be seen that the free edge of the ange g abuts against the free edge of the packing strip h and thus serves to seal the crank between the flange g and the inner face of the door throughout the entire height of the door.

W'ith the construction described and shown, it will be observed that I not only thoroughly stiften the rear edge of the door, but I also provide for an effective seal against water and air throughout the height of the door. I also provide elfectively for drawing the door, during the act of closing it, to a sealed position against the post, this being done without employing a cam plate extending the full height of the door, but on the contrary by employing a series of separated Cain plates, these separated cam plates being advantageous in that they are less liable to be bent sufficiently to interfere with the proper closing of the door, and at the sanie time aifoiding a saving in metal.

Having thus described iny invention, what I claim is:

In a boX-ear-door structure, the combination of a ear Wall, a post structure, an abutment plate aiixed to the post structure eX- tending beyond the face ot' the ear Wall and provided with a flange alongv its front edge, a sliding door having an angle iron aiiixed to its rear edge, one flange or plate of this angle iron extending along the innei1 face Copies of this patent may be obtained for ot the door, a series of separated cani plates projecting beyond the inner edge o the aforesaid flange of the angle iron, and a packing strip clamped between said flange and the inner face of the door and projecting beyond the inner edge of the ange and adapted to Contact with the edge of the Yliange on the car Wall When the door is closed.

In testimony whereof I hereunto afliX my signature in the presence of two Witnesses.
